What is the abiltiy of using TV as DSO or Spectrum analyzer?

Did anyone try with it before?
Share knowledge and ideas..

Thank you IanP,
Nice topic, but very low frequency... (Only up to 20KHz)

Theoritically, Can't I obtain higher frequency range :?::!:

The most significant limitation is the input bandwidth (frequency range). The maximum frequency signal that the unit can display is 20KHz. This is due primarily to the A-D convertor used, faster 8 bit convertors are available but are considerably more expensive than the device used. Although this means the unit cannot be used with microprocessors, it is still useful for audio work, and digital projects which operate at lower frequencies.

You can consider a unit that will employ a PC with a super-fast AD card, and , of course, a composite video output, and with it you can go almost anywhere you like ..
But I don't think this is what you are aiming at, or, is it?
